ERAS'IUS E. WINKLEY, 0F LYNN, MASSACHUSETTS, ASSIGNOB TO UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

SOLE-LEVELING MACHINE.

To all whom it may concern:

Be it known that I, ERASTUS E. WINK- LEY, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Sole-Leveling Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

In Letters Patent of the United States No. 555,5 i8, granted March 3, 1896, is described an automatic sole leveling machine which has become well known to those skilled in the art, having shoe supporting jacks, leveling rolls, and actuating mechanism and automatic devices for controlling the movements of these parts. In this machine the inclination of the leveling rolls is automatically changed as the operation of the rolls is transferred along the shoe, since the form of the shoe at the shank difl ers from that of the forepart and renders such change necessary. To cause each portion of the sole to be acted upon by the roll when at the proper inclination, the machine is provided with cam-actuated mechanism for moving the ack, the cam being so designed as to move the jack and the shoe to the proper point at the proper time. The connections between the jack and its cam mechanism are so constructed that the length of the entire path of movement of the jack may be varied to suit different lengths of shoes, while preserving the same proportional lengths of movement for the forepart and the shank, so that, with shoes of the same style each point on the sole will be reached at the time when the roll is at an inclination to act properly thereon whatever the size of the shoe.

Owing to the difference in various styles of shoes with respect to the relative lengths of the forepart and shank, it has been found necessary, in operating the machine above described to provide for variations in the operation of the jack-actuating mechanism to accommodate the machine to such different styles, and this has heretofore been accomplished by changing the jack-actuating cam, or removable portions of it, so as to vary the relative lengths of throw of the Specification of Letters Patent.

Serial No. 410,507.

parts of the cam corresponding to the shank and the forepart. This involves objectionable inconvenience and loss of time, and the present invention has for its object the production of an automatic sole leveling machine, comprising a sole leveling roll and a shoe supporting jack, which can be adapted for operation upon various styles of shoes, differing in respect to the relative lengths of the forepart and shank, by means of a simple adjustment of mechanism not involving the substitution of cams or other parts.

With the above object in view, the present invention contemplates the provision in a sole leveling machine provided with a shoe supporting jack and a sole leveling roll, of means for varying the operation of the mechanism which changes the relative longitudinal position and lateral inclination of the roll and jack, in such manner as to compensate for variations in the relative lengths of the forepart and shank of shoes of different styles.

Broadly considered the invention contemplates varying the operation of any portion of the actuating mechanism of the machine so as to cause the portion of the shoe sole near the juncture of the shank and forepart to be properly acted upon by the roll regardless of the relative lengths of the forepart and shank.

To avoid a departure from the general mode of operation of existing sole leveling machines of the class to which the present invention relates, as well as to avoid as much as possible increasing the number of operating parts, or adding to the complication of the machine, it is preferred to vary that portion of the actuating mechanism which relatively actuates the jack and roll to transfer the point of operation along the sole. In the simplest and most eificient form of the invention which has as yet been devised, the jack is actuated to transfer the point of operation of the roll along the sole, as in the machine of Patent No. 555,548, hereinbefore referred to, and the mechanism for actuating the jack 1s provided with means of adjustment whereby the time in the operation of the machine at which the juncture between the forepart and shank is reached by the roll can be determined. and

the jack can be actuated to bring the portion of the sole near the juncture of the forepart and shank beneath the roll while the roll is at an inclination to act properly on this portion of the sole.

The mechanism hereinafter described for changing the relative longitudinal position of the ack and roll, and the means for varying the operation of this mechanism, are also applicable to other automatic machines for operating upon the soles of shoes, in which it is necessary or desirable to eifectchanges in the relative position of the parts of the machine for operation upon the shank and forepart, and it is accordingly considered that certain features of the invention, except as defined in the claims, are not limited to use in any particular kind of automatic shoe working machine.

In addition to the features of invention above referred to, the present invention also consists in certain devices, combinations and arrangement of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art from the following description.

The several features of the present invention will be clearly understood from an inspection of the accompanying drawings in which- Figure 1 is a view in sideelevation of a sole leveling machine embodying the same in their preferred form. Fig. 2 is a view in side elevation of the opposite side of the machine to that shown in Fig. 1. Fig. 3 is a view in side elevation on an enlarged scale of a portion of the machine including the jack actuating mechanism. Fig. 4 is a detail view of a portion of the mechanism illustrated in Fig. 3. Fig. 5 is a plan view of the right hand side of the machine wit-h certain parts removed. Fig. 6 is a horizontal sectional view of the lower part of the machine showing particularly the coupling pin shifting mechanism. Fig. 7 is a detail view in front elevation, partly in section illustrating the jack actuating mechanism, and Fig. 8 is a horizontal sectional detail view of the coupling pin shifting mecha- I11S111.

Except for the mechanism which constitutes the illustrated embodiment of the present invention, the machine illustrated in the drawings is substantially the same in construction and mode of operation as the machine described in Patent No. 555,548, hereinbefore referred to, comprising two shoe supporting jacks, two vibrating sole leveling rolls cooperating respectively therewith, mechanism for oscillating thejacks to change the relative longitudinal position of the jacks and rolls, means for connecting and disconnecting each jack and the jack oscillating mechanism, and means for tipping the rolls to change the relative lateral inclination of each jack and its cooperating roll during the leveling operation.

The leveling rolls are mounted in the machine and vibrated and tipped laterally in the same manner and by the same mechanism as in the machine of Patent No. 555,548, to which patent reference may be had for a complete disclosure of the construction and mode of operation of this mechanism as well as the other parts of the machine indicated in the drawings accomaanying this application and not hereinafter specifically described.

Thev shoe supporting jacks are indicated at 1 and are pivotally mounted upon a rock shaft 2 so that the jack, which is in operation, may be oscillated to cause its coiiperating roll 3 to operate upon the entire fore, part and shank of the shoe sole. The means for connecting and disconnecting each ack and its actuating mechanism is the same as in the patented machine and for this reason is not illustrated in the drawings and need not be described. The rock shaft 2 is provided with the usual depending arm 4 by which it and the acks are actuated, and this arm is provided with a curved slot 5, engaged by a slide block 6, which is secured in place by a latch 7, engaging teeth 8 on the arm. The slide block 6 is connected with a link 9, pivoted at 10 to the cam lever 11, which is pivoted at its lower end at 12- on the frame of the machine. A cam 13 mounted upon the cam shaft 36 of the machine actuates the cam lever and through the connection just described, the jacks. The cam 13 is so shapedthat during the operation of the machine, the jack, which is in operation, is first moved inwardly to cause its coiiperating leveling roll to traverse the forepart and shank of the shoe from the toe to the breast of the heel. The jack is then moved outwardly and inwardly to cause the leveling roll to travel back and forth over the shank of the shoe from the breast of the heel to the juncture of the shank and forepart and back again to the breast of the heel, and is then moved outwardly to cause the leveling roll to again traverse the shank and the forepart from the breast of the heel to the toe. During these movements of the jack the inclination of the leveling roll is changed to cause one side of both theforepart and shank to be properly leveled. The inward and outward movements of the jack, above described, are then repeated, while the inclination of the leveling roll is changed to properly level the opposite margin of the forepart and shank.

The jack actuating mechanism as so far described, is similar to the jack actuating mechanism of the machine of the patent above referred to. The present machine differs from the machine of the patent, however, in the connections between the cam lever 11 and the cam 13. In the patented machine the cam roll is mounted directly upon the cam lever so that the movements of the jack are determined solely by the cam, subject to the variations in their amplitude secured by the adjustable connection of the link 9 and the slide block 6 with the arm 4, for the purpose of adjusting the machine for operation upon shoes of different sizes. This adjustment of the machine, however, does not adapt the machine for operation upon different styles of shoes differing in respect to the relative length of the shank and forepart, since the adjustment, while increasing or decreasing the amount of the traversing movement of the roll taking place while the roll is tipped for operation on the shank, does not vary the proportion of this portion of the traversing movement to the entire traversing movement of the roll. To vary the proportion of the traversing movement of the roll, taking place while the roll is tipped for operation on theshank, and thus adapt the machine for operation upon shoes of different styles, the cam roll 14 of the present machine is not mounted directly upon the cam lever 11 but is connected there with through interposed compensating mechanism operating automatically to affect the relative movements of the cam lever and the cam roll so as to vary the efiect of the cam upon the ack actuating mechanism. To provide for variations in the relative lengths of the forepart and shank on both the inside and outside margin of the shoe sole, the compensating mechanism is so con structed and arranged that it can be adjusted to vary independently the proportion of the traversing movement of the roll taking place while the roll is operating on the inside and outside margins of the shank.

The compensating mechanism above referred to include a bell crank lever 15 carrying the cam roll 14 and pivotally mounted at 16 upon the cam lever 11. The horizontal arm 17 of the bell crank lever is con nected by a link 18 with a lever 19 pivoted at 20 upon the frame of the machine. The forward end 21 of the lever 19 (see Fig. 8) is located between bosses 22 on the lower ends of links 23 and 24-which extend upwardly and are pivotally connected with curved arms 25 and 26, by means of slide blocks 27 and 28 located. in clove-tailed slots in the arms 25 and 26, as shown in Figs. 4 and 7. Links 30 connect the lower ends of the links 23 and 24 with the pivotal support 20 of the lever 19, so as to cause the bosses 22 to move always on arcs concentrio with the arc of movement of the forward end 21 of the lever 19. The arm 26 is pivoted at 29 on the frame of the machine and the arm 25 is pivoted on another portion of the frame but co-axially with the arm 26. The arms 25 and 26 are provided with upward extensions carrying cam rolls 31 and 32 respectively, which engage cams 33 and 34 on the cam shaft of the machine. The forward end 21 of the lever 19 is provided with a transverse recess in which is located a sliding coupling pin 38, which may be moved longitudinally to engage alternately the recesses 39 in the bosses 22 on the lower ends of the links 23 and 24. The pin 38 is so moved by means of a pin 40 passing through a slot 41 and having a head engaging a vertical slot in an arm 42 depending from a slide 43 mounted upon fixed horizontal rods 44 on the frame of the machine. The slide 43 carries an upward extension 45 upon which is mounted a cam roll 46 engaging a cam path 47 in the cam 34, as shown in Figs. 7 and 8.

It will be seen that during the operation of the cam lever 11 by the cam 13, if the cam roll 14 he held in constant position with relation to the cam lever, the latter will move exactly in conformity with the cam path. This will be substantially accomplished so long as relative movement of the bell crank lever 15 upon the cam lever is prevented, but any relative movements of the bell crank lever and the cam lever which may occur will modify the movements of the cam lever in proportion to their extent. Such movements are imparted to the bell crank lever by means of the connections comprising the link 18 lever 19, link 23 or 24 and the cam mechanism connected with these links. The amplitude of movement imparted to the links 23 and 24 depends upon their position in the curved slots in the arms 25 and 26, and in order that this may be conveniently adjusted by the operator while at the front of the machine these links are connected by links 50 and 51 with nuts 52 and 53 longitudinally movable upon adjusting screws 54 and 55, at the front of the machine which are provided with keyed stems 56 for the reception of a wrench or crank, and confined against longitudinal movement in a casing 57 mounted on the frame of the machine. By turning the stems 56 the links 23 and 24 may be moved from one extremity to the other of the curved slots so as to vary the effect of the mechanism upon the bell-crank lever 15 from nothing to a maximum.

The operation of the machine will be readily understood from the foregoing description. It may be stated, however, that during the first half of the revolution of the cam 13, the coupling pin 33 is in en gagement with. the link 23 and during the remainder of the revolution of the cam, the coupling pin is in engagement with the link 24. The bell crank lever 15 is thus controlled by the cam 33, while one margin of the shoe sole is being operated upon, and by the cam 34 while the other margin of the sole is being operated upon. It will be apparent from an inspection of Fig. 3, that the cams 13, 33 and 34 are so shaped and so arranged with relation to each other that the bell crank 15 is moved with relation to the lever 11 during the short outward and inward movements of the jack and during the final outward movement of the jack. During the short outward and inward movements of the jack and during the first portion of the long outward movement of the jack, the leveling roll is inclined for operation on the shank, and by adjusting the extent of the movements imparted to the bell crank 15 it will be obvious that the extent of the movement of the jack while the roll is so inclined can be varied to suit the length of shank in the shoe being operated upon. It will also be evident that since the movements of the bell crank are controlled by the cam 33 when one margin of the sole is being operated upon and by the cam 34 when the other margin is being operated upon, that the extent of the movements imparted to the jack can be varied independently for the opposite sides of the shank. The total length of throw of the jack is, however, not affected, since the cams 33 and 34 are so formed as to return the parts including the bell crank lever to their original position before the inward movements of the jack are completed.

In the machine of the present application, as in the machine of the patent hereinbetore referred to a change is made in the inclination of the roll as the roll passes from the shank to the forepart, and this change occurs at a predetermined time in the operation of the machine. The compensating mechanism of the machine of the present application enables the jack actuating mechanism to be so adjusted as to vary the point on the sole at which a change is made in the inclination of the roll. The time during the operation of the machine at which the juncture of the shank and torepart is reached by the roll can thus be determined and the juncture of the shank and forepart can be brought beneath the roll at the time a change is made in the inclination of the roll regardless of variations in the relative length of the shank and torepart.

The cams 33 and 34 are provided with cam paths similar in form, but the links 23 and 24, are differently adjusted in their arms 25 and 26 according to the difference in form of the outside and inside margins of the shoe sole. These cams are also so formed that when the cam 13 completes a half revolution and the sole leveling roll is at the toe of the shoe, the cam rolls 31 and 32 and the arms 25 and 26 are in the same position, that is, the position illustrated in Fig. 4 and since'the curved slots in the arms are at such time concentric, it follows that whatever the adjustment of the slide blocks 27 and 28, the bosses 23 will at such time, be in alinement so that the coupling pin 38 may engage either of them.

To enable the machine to operate to better advantage on extremely small sizes of shoes the lever 11 is provided with a hole so that the link 9 can be pivotally connected to the lever at this point instead of at the point 10 whenever the shoes being operated upon are of a size to make this change advisable.
